What the LPH86-ST430 does in a room
The Dahua LPH86-ST430 is an 86-inch interactive whiteboard from the ST430 Series. It combines a 4K LCD panel, infrared touch, an Android 14 system and two built-in speakers in one black metal casing, so a presenter can run a lesson or meeting without a separate computer.
Display, touch and processing
The 16:9 screen uses DLED backlighting, a typical brightness of 400 cd/m² and a 178° viewing angle horizontally and vertically. The 4 mm anti-glare tempered glass front, rated at 9H surface hardness, helps limit reflections from windows and ceiling lights. Touch is infrared with a zero air gap attachment and ±1.5 mm accuracy, registering up to 40 points on Windows and 32 on Android. Writing works with a finger or the magnetic stylus supplied.
A quad-core Cortex-A73 processor at 1.5 GHz, with 8 GB RAM and 128 GB storage, runs Android 14. Chrome, YouTube and the Google Play Store come pre-installed, and the system carries Google EDLA certification. The two 20 W speakers form a 2.0 channel system covering 140 Hz to 20 kHz.
Connectivity for teaching and meeting rooms
The ports allow several sources to feed the panel:
- Three HDMI IN inputs, one at the front and two at the rear, each supporting 4K at 60 Hz
- An OPS slot for a plug-in computing module, plus a rear USB 3.2 Gen1 Type-A port
- A front USB-C port for data transmission with 5 V 1 A charging
- Two USB Touch Type-B ports, so touch input can be passed back to a connected computer
- A wired RJ-45 port at 10/100 Mbps, RS-232 for control, and Wi-Fi 802.11 a/b/g/n/ac/ax with Bluetooth 5.4
Where it fits across Qatar
A private school in Al Rayyan fitting out a new secondary classroom could use the 86-inch format for whole-class teaching, running lesson apps on Android and connecting a teacher laptop to the front HDMI input. A training room in Education City could pair the panel with the OPS module and the wired network port for hands-on sessions. In a West Bay boardroom, the rear HDMI inputs and wireless connectivity let a laptop share content during calls with teams abroad.
Environment matters in Qatar. The operating range is 0 °C to +40 °C, with storage between –10 °C and +50 °C and humidity of 10% to 90%. Summer temperatures can exceed 45 °C, so the panel belongs in an air-conditioned room, away from direct sunlight and from lobby doors where dust storms can enter. Power is rated at 100–240 VAC, 50/60 Hz, which covers Qatar's 240 V supply. Typical consumption is 237 W, rising to 370 W at maximum, with standby draw of 0.5 W or less.
